Basic functions and requirements of DC regulated power supply
An electronic device that can provide a stable DC power supply to a load. The power supply of the DC stabilized power supply is mostly AC power supply. When the voltage of the AC power supply or the load resistance changes, the DC output voltage of the voltage stabilizer will remain stable. DC stabilized power supply With the development of electronic equipment in the direction of high precision, high stability and high reliability, high requirements are put forward for the power supply of electronic equipment.
Introduction to DC regulated power supply
In today's society, people greatly enjoy the convenience brought by electronic equipment, but any electronic equipment has a common circuit - the power circuit. From supercomputers to pocket calculators, all electronic devices must be supported by power circuits to work properly. Of course, the style and complexity of these power supply circuits vary widely. The power circuit of a supercomputer is itself a complex power system. Through this power system, all parts of the supercomputer can receive continuous and stable power supply that meets various complex specifications. A pocket calculator is a much simpler battery-powered circuit. But don't underestimate this battery power supply circuit. The relatively new circuit is fully equipped with advanced functions such as battery energy reminder and power-down protection. It can be said that the power circuit is the basis of all electronic equipment, without the power circuit, there would be such a wide variety of electronic equipment.
Due to the characteristics of electronic technology, the requirement of electronic equipment for power supply circuits is to be able to provide continuous and stable power that meets the load requirements, and usually requires stable DC power. The power supply that provides this stable DC power is a DC regulated power supply. DC regulated power supply occupies a very important position in power supply technology. In addition, the first thing many electronics enthusiasts encounter at the beginner stage is to solve the power supply problem, otherwise the circuit will not work, electronic production will not be possible, and learning will be out of the question. For this reason, pecker'sHome has specially opened up this topic on DC regulated power supply technology, hoping to give some help to beginner electronics enthusiasts. At the same time, it can also be used as a reference material for ordinary enthusiasts in terms of power supply technology, for daily study and reference in production.
Basic functions and requirements of DC regulated power supply
1. The output voltage value can be set arbitrarily and work normally below the rated output voltage value.
2. The steady current value of the output current can be set arbitrarily below the rated output current value and work normally.
3. The voltage and current status of the DC regulated power supply can be automatically switched and have corresponding status indications.
4. Accurate display and identification are required for the output voltage and current values.
5. For DC regulated power supplies with precise requirements for the sum of output voltage and current, generally multi-turn potentiometers and voltage and current fine-tuning potentiometers are used, or direct digital input is required.
6. There must be a complete protection circuit. The DC regulated power supply should not be damaged when a short circuit occurs at the output end or in an abnormal working state, and it can work normally immediately after the abnormal situation is eliminated.
